One bout of a natural song, duplicated. Bird not seen while singing but a Sittasomus was seen moving between trees from the general source area of the sound. Sound from this species confirmed subsequently with fieldwork. Specimens taken. Bird was singing ~12m off the ground in the upper midstory of a mature cloud forest. Reported in: Cuervo, A. M. et al. 2008. Avifauna of the northern Cordillera Central of the Andes, Colombia. Ornitología Neotropical 19:495–515

Documentation of northernmost range extension for this species (one of several records after the 2008 paper:. Male confirmed visually. In the midstory-subcanopy of tall mature humid montane forest (pluvial premontane forest), in the forest interior near a tree fall gap.

Male (visual confirmation) ~ 2m from mic. Calls after playback of the its own (duet) loudsong. At the edge of montane cloud forest (a trail north of the road) - in a patch of dense shrubby vegetation with climbing plants and chusquea bamboo.

Recording archived at IAvH-BSA 19217 (Colección de Sonidos-Instituto Humboldt). One or maybe two individuals in this recording, which includes a natural song bout and two calls (at 7.5 and 26.5 sec). This was made in a ridge in the middle of a continuous cloud forest at 1550 m. Bodega Vieja is the type locality of this "Antioquia Myiopagis" and one of several cloud forest sites in the Amalfi-Anorí region of the northern Central cordillera where we've discovered this rare bird, which was provisionally reported as M. caniceps (rightly so!) in Ornitología Neotropical {2008}19:495–515. In Amalfi, adults "M. olallai" look like this - and quite similar to specimens from the Serranía de Perijá. Check out our forthcoming paper in Zootaxa

Recording archived at IAvH-BSA 19187 (Colección de Sonidos-Instituto Humboldt). A bird in the canopy of a heavily disturbed small fragment (19 Ha.). This was in an Andean, mid-elevation cloud forest at 1550 m at the northern end of the Central cordillera. A short segment of its voice was used for playback but elicited very little or no response. Co-workers and I have documented this bird (as "M. caniceps") in the Amalfi-Anorí region between 1300-1850 m (see Ornitología Neotropical {2008}19:495–515). And this is how this "Antioquia Myiopagis" look. The question is, how do they sound in Serranía de Perijá?

Recording archived at IAvH-BSA 19580 (Colección de Sonidos-Instituto Humboldt). Two song bouts of the same individual. These recordings were made in a large fragment of pluvial premontane forest. Bosque Guayabito is one of several cloud forest sites in the Amalfi-Anorí region of the northern Central cordillera where we've discovered this "Antioquia Myiopagis", which was provisionally reported as M. caniceps (rightly so!) in Ornitología Neotropical {2008}19:495–515. A specimen (eventually the paratype) was taken at this locality on 4 January 2005: does it look to you like a M. olallai? The holotype is from a different locality, also in Amalfi.
